These are the latest spy shots with the 2014 Audi A3 Cabrio which we believe will be showcased at Frankfurt Motor Show in September.

These are the latest spy shots with the 2014 Audi A3 Cabrio which we believe will be showcased at Frankfurt Motor Show in September.

The soft-top version of the A3 will ride on Volkswagen's MQB platform which underpins the A3 hatchback and sedan, Golf VII, Seat Leon and Skoda Octavia. It will be a competitor for the upcoming BMW 2-Series Cabrio and should carry some of the styling cues implemented in the A3 Sedan.

It will borrow the engine lineup from the regular A3 so there will be a 1.8-liter TFSI outputting 180 HP (132 kW) and a 2.0-liter TDI available with 150 HP (110 kW) and 184 HP (132 kW). An S3 Cabriolet is likely in the pipeline with 300 HP, followed by the range-topping RS3 Cabrio churning as much as 400 HP (294 kW) from a turbocharged five-cylinder, 2.5-liter mill.

All versions will come as standard with a six-speed manual transmission, while the S3 Cabrio should be optionally available with a six-speed dual-clutch 'box. The RS3 Cabrio will probably be sold with an optional seven-speed DSG.
